I've tried UnDot(), but it do nothing.

try blindpp or mpeg2source's internal deblock/dering:

either:

mpeg2source("my blocky HDTV cap.d2v",cpu=4)

or:

mpeg2source("my blocky HDTV cap.d2v",cpu=0)

blindpp(quant=8,cpu=4)

should do the trick.

sometimes the internal deblock (as it reads the per-frame quants, which vary quite a bit) can cause different amounts of blur to hit each frame, which may be undesirable. blindpp doensn't suffer this, but may miss a lot of blocks because of it (or oversmooth).

if you're downscaling to SDTV sizes, either will be fine. make sure you do it before resizing though.
